Minneapolis musician Mark Mallman woke up at 3 a.m. with a crushing panic attack that wouldn’t end. He responded by pouring songs into a happiness playlist and leaning on the wisdom of friends. His new book is the true story of a man beset by grief, healed by music, and learning to laugh through it all. Mallman is a songwriter, composer , and performer from Minneapolis. He has recorded eight albums and his music has been enjoyed by audiences around the world. His non-stop, non-sleep “Marathon III” performance stretched 78 hours and included 576 pages of rhyming lyrics. Mallman’s album “The End is Not The End” is a deliberate meditation on overcoming the roots of despair.
